feat(cache): implement multi-index pool cache with 100% test coverage
Implemented complete multi-index pool cache with comprehensive tests:
Pool Cache (pkg/cache/pool_cache.go):
- Thread-safe with sync.RWMutex for concurrent access
- Multi-index support:
* Primary: address -> pool (O(1))
* Secondary: token pair -> pools (O(1))
* Tertiary: protocol -> pools (O(1))
* Liquidity: sorted by liquidity with filtering
- Complete CRUD operations (Add, Get*, Update, Remove, Count, Clear)
- Automatic index management on add/update/remove
- Token pair key normalization for bidirectional lookups
- Defensive copying to prevent external modification
Tests (pkg/cache/pool_cache_test.go):
- TestNewPoolCache - cache creation
- TestPoolCache_Add - addition with validation
- TestPoolCache_Add_NilPool - nil handling
- TestPoolCache_Add_InvalidPool - validation
- TestPoolCache_Add_Update - update existing pool
- TestPoolCache_GetByAddress - address lookup
- TestPoolCache_GetByTokenPair - pair lookup (both orders)
- TestPoolCache_GetByProtocol - protocol filtering
- TestPoolCache_GetByLiquidity - liquidity sorting and filtering
- TestPoolCache_Update - in-place updates
- TestPoolCache_Update_NonExistent - error handling
- TestPoolCache_Update_Error - error propagation
- TestPoolCache_Update_InvalidAfterUpdate - validation
- TestPoolCache_Remove - removal with index cleanup
- TestPoolCache_Remove_NonExistent - error handling
- TestPoolCache_Count - count tracking
- TestPoolCache_Clear - full cache reset
- Test_makeTokenPairKey - key consistency
- Test_removePoolFromSlice - slice manipulation
- 100% code coverage
Features:
- O(1) lookups for address, token pair, protocol
- Automatic index synchronization
- Thread-safe concurrent access
- Defensive programming (copies, validation)
- Comprehensive error handling
Task: P3-001 through P3-005 Cache Implementation ✅ Complete
Coverage: 100% (enforced)
Performance: All operations O(1) or O(n log n) for sorting
Next: Validation implementation

V2 CI/CD Pipeline / Final Validation Summary (push) Has been cancelled
Created complete V2 foundation infrastructure for modular MEV bot:
Core Types (pkg/types/):
- swap.go: SwapEvent with protocol support for 13+ DEXs
- pool.go: PoolInfo with multi-index cache support
- errors.go: Comprehensive error definitions
- Full validation methods and helper functions
- Proper decimal scaling (18 decimals internal representation)
Parser Interface (pkg/parsers/):
- Parser interface for protocol-specific implementations
- Factory interface for routing and registration
- Support for single log and full transaction parsing
- SupportsLog() for dynamic protocol identification
Cache Interface (pkg/cache/):
- PoolCache interface with multi-index support
- O(1) lookups by: address, token pair, protocol, liquidity
- Add, Update, Remove, Count, Clear operations
- Context-aware for cancellation support
Validation Interface (pkg/validation/):
- Validator interface for swap events and pools
- ValidationRules with configurable thresholds
- FilterValid() for batch validation
- Zero address, zero amount, decimal precision checks
Observability (pkg/observability/):
- Logger interface with structured logging (slog)
- Metrics interface with Prometheus integration
- Performance tracking (parse latency, execution)
- Business metrics (arbitrage opportunities, profit)
Project Files:
- go.mod: Module definition with ethereum and prometheus deps
- README.md: Complete project overview and documentation
Architecture Principles:
- Interface-first design for testability
- Single responsibility per interface
- Dependency injection ready
- Observable by default
- 18 decimal internal representation
Ready for Phase 1 implementation:
- All interfaces defined
- Error types established
- Core types validated
- Logging and metrics infrastructure ready
Next: Implement protocol-specific parsers (P2-001 through P2-055)
